    The SAURON project - XVI. On the sources of ionization for the gas in elliptical and lenticular galaxies
    Following our study on the incidence, morphology and kinematics of the ionized gas in early-type galaxies, we now address the question of what is powering the...

    The SAURON project - XVII. Stellar population analysis of the absorption line strength maps of 48 early-type galaxies
    We present a stellar population analysis of the absorption line strength maps for 48 early-type galaxies from the SAURON sample. Using the line strength index...
  • Publication
    The SAURON project - XVIII. The integrated UV-line-strength relations of early-type galaxies
    Using far-ultraviolet (FUV) and near-ultraviolet (NUV) photometry from guest investigator programmes on the Galaxy Evolution Explorer (GALEX) satellite, optical...
  • Publication
    The SAURON project - XX. The Spitzer [3.6] - [4.5] colour in early-type galaxies: colours, colour gradients and inverted scaling relations
    We investigate the [3.6]-[4.5] Spitzer-IRAC colour behaviour of the early-type galaxies of the SAURON survey, a representative sample of 48 nearby ellipticals...
  • Publication
    The SAURON project - XXI. The spatially resolved UV-line strength relations of early-type galaxies
    The unexpected rising flux of early-type galaxies at decreasing ultraviolet (UV) wavelengths is a long-standing mystery. One important observational constraint...
  • Publication
    The scaling of X-ray variability with luminosity in ultra-luminous X-ray sources
    Aims: We investigate the relationship between the X-ray variability amplitude and X-ray luminosity for a sample of 14 bright ultra-luminous X-ray sources (ULXs)...
  • Publication
    The scatter of the M dwarf mass-radius relationship
    M dwarfs are prime targets in the hunt for habitable worlds around other stars. This is due to their abundance as well as their small radii and low masses and...
  • Publication
    The Scattering Polarization of the Lyα Lines of H I and He II Taking into Account Partial Frequency Redistribution and J-state Interference Effects
    Recent theoretical investigations have pointed out that the cores of the Lyα lines of H I and He II should show measurable scattering polarization signals when...
  • Publication
    The Scattering Polarization of the Sr I λ4607 Line at the Diffraction Limit Resolution of a 1 m Telescope
    One of the greatest challenges in solar and stellar physics in the coming years will be to observe the second solar spectrum with a spatial resolution...
